ran into this:
both the egr & the sender pigtail have different color wires than the wiring instructions...

sender has black, grey, & blue

egr has brown, red, grey, purple & white

any suggestions?

thanks,
al

 

edit...forgot the purple egr wire...

 

I have just found the egr harness info for the truck...thanks to cablebandit

from the gm dvd info on the egr harness,
brown 0-5
grey +5vdc
purple gnd


the pin config. of my sender...
http://shed51.com/sensors.htm
which is the same as the AutoMeter fp sender's configuration:


and the pic of my sender pigtail below,



we have come up with this...
sender/pigtail to egr harness

Blk (gnd) to purple (gnd)

Grey (+5vdc)to grey (+5vdc)

Blue (0-5) to brown (0-5)

 

OK guys...someone on LS1TECH caught this before you guys did...

I was looking at the plug end of the pigtail the same as the sender's pin out, which is incorrect because it is actually a mirror of the sender...

so...the correct connections are:

sender/pigtail to egr harness

Grey (gnd) to purple (gnd)

Blk (+5vdc) to grey (+5vdc)

Blue (0-5 signal) to brown (0-5 signal)

 

I got the scan tool set-up to log fp...
sender works great!
